[HH] Mystery signal from a helicopter

[Jerry Feldman]

They used the Bell OH-13 (model 47) 2-bladed helicopter in M.A.S.H. The
"killer Hillers" were two-bladed (semirigid) with wooden blades. I used
to fly the Hiller OH-23 in flight school. Not only were they semirigid,
but they had paddles connected to the cyclic and no hydraulics. The Bell
had hydraulics.
